SELF-LUBRICATING VEHICLE-HUB.

SPECIFICATION forming part of Letters Patent No. 376,152, dated January10,1888.

Application filed J'unr 22, 1887. Sen'al No. 242,181. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN VANBUREN HAW- KEY, a citizen of the UnitedStates, residing at Greensburg, in the county of Westmoreland and Stateof Pennsylvania, have invented ccrtain new and useful Improvements inSelf-Lubricatiug Vehicle-Hubs; and I do hereby declare. the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which itpertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to an improved selflubricating andpit-car-vehiclehub, the object beingto provide means whereby thejournalsof vehicles may be properly lubricated in an automatic manner. This Iaccomplish by cer' tain details of construction and combination ofparts, as will be fully described hereinafter.

In the accompanying diawings, Figure 1 is a vertical sectional elevationof myimproved self-lubricating vehicle hub constructed in accordancewith my invention. Fig. 2 is a transverse vertical section of the same,taken on the line m :c. Fig. 3 is a cross section on the line 3 y.

To put my invention into practice with a 1nine-car wheel such as are nowin common use, I provide a hub, m, of a suitable size and form ofconstruction. at and integral therewith-is an outer casing, which leavesan intermediate annular chamber, b, divided by a partition, Z, providedwith Sn rrounding this hub,

to the linchpin e when it is desired to re move or put the same inposition. At the back or rear of the chamber 1) are a number ofopenings, 0, through thehub m, through which the lubricant passes tothejournal a. At the rear of the hub is an annulargroove, g, whichcollects and retains all waste oil from the axle orjournal bearing a. Inthe chamber b,formed on or attached to the hub, are a number of ribs,72, extending in the directionofthelength of the chamber 12, which serveto retain the lubricant in all parts of the chamber 12 while the same isbeing revolved.

The advantages of this self-lubricating hub are that, having a closedend,f, the oil cannot escape without first passing around the journal a,and also all waste or drip from the journal a is avoided by the samebeing col- &

lected in the groove 9, at the rear of the hub. lfit is desired todisconnect the wheel from the journal (6, the cap i is removed and thepin 6 taken out of its place.

Having thus described my invention,what I claim, and desire to secure byLetters Patent,

A self-lubricatingvehicle-hub having an
